Abstract
There is provided a novel alloy-coated Cu bonding wire that achieves a favorable FAB shape and also a favorable initial bondability of a 2nd bonding part including adhesion of the 2nd bonding part, and that reduces a galvanic corrosion in a high-temperature environment to achieve a favorable bond reliability of the 2nd bonding part. The alloy-coated Cu bonding wire includes a core material of Cu or Cu alloy, and a coating layer having a total concentration of Pd and Ni of 90 atomic % or more formed on a surface of the core material. The bonding wire is characterized in that:
